Application filedli'ehruaty 19, 1927i Serial No. 165L555.

My invention has to do with a guide track for a rolling window screen or the like wherein the screen may be threaded into the guide track after it is accidentally removed there from, by simply moving the screen towards rolled up position.

Still a. further object is to provide a track guide having a tubular portion provided with a slotoxtendinglengthwise thereof and the side edges of a screen having-thickened portionsthereon received in said tubular portion,

the slot in the tubular portion-being of less. diameter than the thickness of the retaining members or thickened portions which are adapted to travel within the tubular portion of the guide track and at the same-time to provide thetubular portion ofthe guide track with aportion or part where the material or wallsof thetubular portion are'spread apart a greater distance than the width of said slot thereby definingan-enlargedopening that if the: side edges and thickened portions of the screen are accidentally withdrawn from the guide track throughithe narrow slot they may reenter the guidetrackthrough the en larged opening and thereafter the side edges of the screen travel up anddown Within the tubular portion of the guide track.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my guide track for screen construction, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of a portion of my guide track with the enlarged opening formed therein and illustrating the screen as it reenters the guide track.

Figure 2 is a side View illustrating the slot in the track as well as the enlarged opening together with a screen casing or housing in communication with the upper end of the track itself.

In the accompanying drawings I have used the reference numeral 10 to indicate generally a sheet metal casing in which may be mounted a rolling window screen 12. The screen 12 passes out of the casing 10 through a slot opening 14 formed in the casing 10.

The screen has adjacent its side edges a plurality of clips 16 which may be referred to as thickened portions. The clips 16 are comparatively large and form retaining members forthe side edges of the screen when traveling inthe guide tracks as will hereinafter be more fully set forth.

The side edges-of the screen 12 as well. the clips 16 are designed to travel in guide tracks The guide tracks A as illustra ed in the drawings are formed of a single piece of metalbent uponitself-to define a fastening flange 18 formed with slot openings 20 for receiving screws or the like-whereby the track A. may be mounted upon an ordinary window frame or casing.

The track A includes a tubular guide portion 22 having'the free ends of its wallsspaced apart a slight distance for forming a narrow slot 24. The slot 24 extends lengthwise'of the guide track A. As illustrated in the drawings the tubular guide portion 22 is formed with a pair of flat flanges 26 which are spaced apart by the slot 24.. The screen12 travelsbetween the flanges 26; y

The clips 16 are of greater size than the normal width of the slot24; so that asa matter of fact, the clips: 16 serve to retain'the side edge of the screen 12 within the track- A. The tubular portion 22 will, of: course, spread apart a littledistance so that the width of the slot2t may be increased-when undue pressure is-exerted against the screen 12 and when thisoccurs, the side edge of the screen together with the clips 16 will pass through the slot 24 as illustrated by the reference character B.

The tubular portion. 22 which serves to guide the side edges of the screen is somewhat resilient. As a result of this resiliency the slot in the tubular port-ion will give or spread rather than mutilate or tear the clips 16 from the side edge of the screen 12 when undue pressure is applied against the screen.

Normally however, the slot 24 does not al- 5 low the clips 16 to pass therebetween. In order to have the side edges of the screen 12 and the clips 16 pass back into the guide track after they have been pulled accidentally from the guide portion 22, I provide an enlarged opening 28 which is formed by spreading the walls of the tubular portion 22 a. greater distance apart than the normal distance of the width of the slot 24.

The opening 28 is large enough to permit the screen to rethread into the guide track A with the clips 16 passing into the tubular portion 22 through the opening 28. It may here be mentioned that after the screen and its thickened portions or clips have been V I from its guide track it usually has a portion of the screen still remaining in the guide track and when the screen is rolled up; the

punched out portion as at B will pass into the tubular portion 22, through the opening 28 and then when the screen is withdrawn or pulled down, the entire side edge of the screen will pass into the tubular portion 22 below the opening 28.

It will be noted that the opening 28 is formed by simply spreading the walls of the guide track A. a short distance and that the opening is hardly noticeable and will not in any way interfere with maintaining a fly tight screen connection between the guide track and the side edges of the screen.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

1. A guide track for a flexible roll screen having a tubular portion provided with a slot extending lengthwise thereof for receiving the side edge of the screen and allowing it to travel in the guide track as it is rolled up and down, the material of said tubular por tion for a part of its length being spread apart a greater distance than the width of said slot defining thereby an enlarged opening, where- 'by if the side edge of the screen normally traveling in said track is accidently withdrawn from the guide track, it may travel back into the guide track through said enlarged opening as the screen is rolled up.

2. A guide track for a flexible roll screen having a tubular portion provided with a slot extending lengthwise of the guide track for receiving the side edge of the screen and allowing it to travel in the guide track as it is rolled up and down, the material of said tubular portion. at points spaced from the ends thereof being spread apart a greater distance than the width of said slot defining thereby an enlarged opening whereby if the side ed e of a screen normally traveling in said track is accidently withdrawnfrom the guide track it may automatically travel back into the guide track through said enlarged opening as the screen is rolled up.

A guide track for a flexible roll screen having a tubular portion provided with a slot extending lengthwise of the guide track for receiving the side edge of the screen and allowing itto travel in the guide track as 1t is rolled up and down, the material of said tu-.

bular portion at a point spaced from the upper end thereof being spread apart a greater distance than the width of said slot defining thereby an enlarged-opening whereby it the side edge of a screen normally traveling in said track is accidently withdrawn from the guide track it may automatically travel back into the guide track through said enlarged opening as the screen is rolled up the upper half of said enlarged opening having sides inclined towards each other.
